Integrated Duckweed-based Wastewater Treatment and Pisciculture

Situated in the central Bangladeshi district of Tangail, Mirzapur is a town with an estimated resident population of around 20,000. The town gained popularity for its Kumudini Welfare Trust Hospital, which was considered the largest hospital in the country during the time of its construction.

The hospital complex has an estimated wastewater volume equivalent to a population of about 2,000 to 3,000. The generated volume is sourced from the hospital, school, and staff quarters.

In recognition of the inadequacy of the existing, aid-funded 4-cell facultative wastewater treatment system to treat the wastewater treatment requirements of the hospital complex, the Mirzapur Shobuj Shona (Green Gold) project was conceived. The initiatitive was spearheaded by the Project in Agriculture, Rural Industry Science and Medicine (PRISM)-Bangladesh, a local nongovernmental organization (NGO).
